Answer:
Mass movement
Explanation:
Mass movement refers to the synchronized and sustained contraction of the circular muscles of the colon. It does not follow the pattern of peristaltic waves.
The mass movement occurs immediately after the intake of a meal and serves to force the colonic content to move into the rectum. The result is the stimulation of defecation reflex.
The mass movement is triggered by overdistension of the colonic segment and/or gastrocolic reflex.
